IDA Library Python module

IDA Library Python Module

The IDA Library Python module enables running IDA Pro as an independent Python package outside the IDA UI environment, allowing for programmatic binary analysis and reverse engineering tasks.

Prerequisites

Environment Setup

Set the IDADIR environment variable to point to your IDA installation directory:

Linux/macOS:

export IDADIR="/path/to/your/ida/installation"

Windows:

set IDADIR="C:\Program Files\IDA Pro 9.1"

Example paths:

• macOS: /Applications/IDA Professional 9.1.app/Contents/MacOS/
• Windows: C:\Program Files\IDA Pro 9.1\
• Linux: /opt/ida-9.1/

Note: If you have already installed and configured the idapro Python package in the past using script provided with IDA installation package, setting IDADIR is not required.

Usage example:

#!/usr/bin/env python3

Type Hints

This package automatically installs type stubs for all IDA Python modules, providing IDE support with autocompletion and type checking for IDA Python modules

Type hints are installed automatically during package installation!

Troubleshooting

Common Issues

ModuleNotFoundError: No module named 'idapro'

• Ensure IDADIR is set correctly
• Verify IDA Pro is properly installed

License Issues

• Ensure you have a valid IDA Pro license
• Check that IDA can run normally in GUI mode first

Type hints not working

• Restart your IDE after installation
• Check that .pyi files exist in your site-packages directory
